Though climate change is an urgent threat, the efforts to counteract it still remain politically divisive. Time is running out.
That’s why a group of researchers is playing the long game, determining solutions for an Earth ravaged even more by erratic weather and lessened sustainability.
To counter extended heatwaves—inevitable if the issue of climate change and rising temperatures go unmitigated—researchers wrote in a paper for Nature Climate Change that dimming the sun’s rays by spraying sulfate aerosols into Earth’s atmosphere would lessen the impending damage.
The phenomenon happens naturally in certain regions when volcanic ash projects into the sky, effectively dimming solar rays.
While the risks of this method are uncertain, the researchers insist that no land mass would be effected more negatively than the effect climate change would have.
However, the plan is being met with criticism from other experts.
Alan Robock, an environmental science professor at Rutgers, told The Atlantic:
“I don’t think it is correct to imply that geo-engineering is a good or safe idea…and there is no way to do what they modeled, as we cannot turn down the sun.”
Robock is referring to the simulations run by the research team, whose simulation ran on reduced solar rays rather than application of sulfate aerosols.
Robock isn’t the only skeptic.
“Most of the climate models project that solar geoengineering could offset most climate change for most people most of the time. But in climate models, if something goes wrong, you can run the model again. In the real world you don’t have that option.”

Exactly. That's one of the many reasons solar geoengineering is so scary. The challenge here is that we have only one Earth and there are risks from CO2 and also risk from CO2 + geo. No risk free choice. https://t.co/t0A722KUys

Rather than planning for imminent doom, maybe we should consider something else.
